Two-Stage Snowblower Skid Shoes
Adjust the skid shoes to allow the required clear-
ance under the blade. On level, paved surfaces,
adjust the skid shoes to allow 3/16 to 1/4 in. (5 to 6 mm) clearance between the cutting edge and the
surface. On uneven or gravel surfaces, allow 1/2
to 5/8 in. (13 to 16 mm) clearance, depending on the size of the gravel. Refer to Skid Shoe Height Ad- justment illustration.

Skid Shoe Height Adjustment
Adjust the tension on the reduction chain as follows:
1.Loosen the four (4) bolts securing the lower sprocket support box to the reduction box hous- ing.
2.Position the lower sprocket support box accord- ing to the amount of chain tension required. The chain should have about 1/4 to 1/2 in. (6 to 13 mm) of slack.
3.To increase the chain tension, position the support box lower. To decrease the chain ten- sion, position the support box higher.
4.Retighten the four (4) bolts securing the support box.
